AUSTIN -- What celebrity chef Rachael Ray has concocted for Saturday at the South By Southwest Music Festival is no 30-minute meal.

Her sixth annual daylong Feedback at Stubb's event, which takes over the famous barbecue restaurant, begins at 10:30 a.m. Saturday and runs through 4 p.m.

Fourteen bands including Macklemore & Ryan Lewis, Eagles of Death Metal, Frightened Rabbit and Delta Rae. Austin's Eastside Memorial High School's Panther Band will perform to open the event; Kenny Loggins will close. The acts will play on Stubb's two outdoor stages.

Ray has cooked up four special recipes that will be served all-day: Tex-Mex Bacon Cheeseburgers with Chipotle Ketchup, Mexican-Style Fried Chicken, Austin BBQ Pulled Pork Tacos and Sweet Corn Soup with Mexican Pesto. The event is free -- as is the food and drink -- and open to the public until it hits capacity, then entry is restricted. (More information on the event's Facebook page; follow @RRFeedback for updates.)

"It really marries music and food," said Ray in an interview before SXSW. "It's who I am when I am not on camera. I love music, all kinds of music."

She and husband, John Cusimano, a lawyer with a rock band, "have an enormous vinyl collection. It's who we are."

For the second year, Ray has hosted a festival-long showcase. Held at Banger's Sausage House & Beer Garden, the invite-only event winds up a four-day run Saturday night that will have included 40 bands and musical acts including ZZ Ward, Youngblood Hawke, The Last Bison and Bear Mountain.
